Although we are used to seeing Saturn's moons lit directly by the Sun, sometimes we can catch them illuminated by 'Saturnshine.' Here, NASA's Cassini spacecraft see Mimas (upper right) lit by light reflected off of Saturn.

NASA's Cassini spacecraft spies Mimas, positioned against the shadow of Saturn's rings, bright on dark. As we near summer in Saturn's northern hemisphere, the rings cast ever larger shadows on the planet.

Among the interplay of Saturn's shadow and rings, Mimas, which appears in the lower-right corner of the image, orbits Saturn as a set of the ever-intriguing spokes appear in the B ring (to the right of center) in this image from NASA's Cassini spacecraft.

This image from NASA's Cassini spacecraft reminds us of how different Mimas and Pandora are when they appear together; although both are moons of Saturn, Pandora's small size means that it lacks sufficient gravity to pull itself into a round shape.

This enhanced-color view of Saturn's moon Mimas was made from images obtained by NASA's Cassini spacecraft. It highlights the bluish band around the icy moon's equator. The large round gouge on the surface is Herschel Crater.

The immense size of Saturn is emphasized in this portrait by NASA's Cassini spacecraft that features the moon Mimas shown in front of the planet. Mimas appears as only a small dot above the rings near the center of the image.

A kingly crescent Saturn rests on the right of this NASA Cassini spacecraft portrait while the moon Mimas appears above the rings on the left. Mimas looks like just a speck of light here but is actually 396 kilometers, or 246 miles, across.

This image shows NASA's Cassini spacecraft's imaging science subsystem visible-light mosaic of Mimas from previous flybys on the left. The right-hand image shows new infrared temperature data mapped on top of the visible-light image.

Appearing like a cyclops gazing off into space, Saturn's moon Mimas and its large Herschel Crater are profiled from NASA's Cassini spacecraft. Herschel Crater is 130 kilometers (80 miles) wide and covers most of the left of this image.
